feet thick. On the salt, beneath the earth,
have been found remains of prehistoric
animals, and Indian relic. Above the salt

sandstone.
In paper on the color of eyes in
France, Mons. Topinard has called at
tention to the extreme rarity OF greenish
eyes in Europe, only six cases having been
observed by Prof. Virchow in 100000
Germans. With US q green-eyed person
must be fully as uncommon sight. Yet
Chinese annals record that green eyes
abound in parts Of ASIA and Pallas notes
that they are met with in Siberia.

Having fresh in mind the discovery that
artificial teeth were used by the ancient
Greeks and Romans, one can hardly feel
surprised at finding that artificial limbs are
no modern innovation. Historians have
vaguely alluded to substitutes for arms
and legs in ante Christian days, but q
specimen of such work is now actually in
existence, and forms a unique relic in the
Museum of the Royal College of Surgeons,
London. 1t is an artificial leg dating
from about 300 B c., and unearthed with
the cripple's skeleton at Capua IN 1885.
1t is made of pieces Of thin bronze, the
lower two-thirdSs having been nailed to q
wooden core-now decayed-and the up
per third being hollow.
Real diamonds have been produced arti'
